Letters Patent No. 107,962, dated October 4, 1870.

To all rwhom it may concern:

Beit known that I, Monrrz Itosnssrnnv, of Boston, -in `thc county ofSuffolk and State .of Massachusetts, have invented a new and usefulImprovement in the Manufacture of Ice; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawing making a part of this specication.

Figure I is a verticalsection of `the apparatus.

Figure II is a perspective view of the'aplmratus used for cooling wineand other liquids.

Figure III is a view of a freezing-vessel.provided with wings.

' Figure 1V is another form of freezing-vessel.

My apparatus for the manufacture of ice consists, mainly, in thefoi-mand construction of various mechanical parts, and also in certainchemical substances to be used in the machine, which, by their solutionand rapid motion,lcause thccongelation of water contained within hollowvessels or cases.

The apparatus is constructed as follows:

A hollow tub or vessel is represented at A, Fig. I. This should be madeof wood or other non-comlucting material. i At the middle of the bottomof this vessel, there is a'step or recess, `to receive the lower end ofthe vertical shalt C, which extends 1.ip\\'ard,'aml passes through ahole in the corel' Z. i

The top'of this shaft has a tcnon or clutch, l), which engages with theprolongation of a short vertical. shaft that is made fast to thegear-wheel J, this tellen being secured in place by the pin I. Theremovable arm G IH turns on the pin-joint L,

. which is supported by the standard F, affixed to the outside of thetub or vessel A.

The upper part of the.` movable arm G is hollow, and receives thehorizontal shaft M, which has at one end the gear-whecl K, and at theother the pulley or wheel O, which `may be turned by a beltfrom asteamcng'ine or other motor, or by the hand applied at the crank l. i

When this is turned, the motion of the gear-wheel K is communicated tothe wheel J, causing the shaft C to revolve.l

' Attached to this sha-ft, by hooks or other convenient fixtures, aretwo, four, or more, metallic cases, R 1t', provided with screw-covers gy'. y,

In the middle of these covers, there are holes7 S S',

which are stopped with a cork or India-rubber stopper, as at T.

`There may be two, four, or more, vanes or arms, Q Q', fastened to theshaft, for the purpose of stirring the liquid contained in the case A,and causing currentsto ilowfreely around the cases It.V W y n The vesselor tub A may have alrontcr covering or tub, as shown, in part, at 16 17,the space between the t-wo vessels being filled with any non-conductorof heat. `This prevents the contact of the outer air with thereigerating-vessel A.

^ When ice is to be made, the cases R are to be filled one pound ofchloride of ammonium, one pound of nitrate of potassa, and one pound ofsulphate of soda,

for each four pounds of water contained in the vessel A. The cover Z isthen put on, the edges of the hole through which the shaft passes, beingclosed by the India-rubber washer E. The arm H G is then turned forwardto its place, the pin I put in, and the shaft, with its attached casesR, is put in rapid rotation by turning the wheel O. In about fifteenminutes`,`the wat-er in the cases is frozen, and the solid ice is to beremoved for use. The necks S allow sulicient space forv the expansion ofthe ice in freezing. A second charge of water-may now be introduced, thetime required for freezing this being longer than for the first charge.f

It' the water that is placed in the vessel A and in the cases is ata,low temperature, the sulphate of soda may not be required.

The saline mixture is to be heated, to evaporate the water, and recoverthe salts, which are then dried, and, after heilig pulverized, are to heused again for freezing successive charges of water.

The form of the cases may be varied at pleasure, as in Fig. 111,6 7 8showing the-central shaft; 4, the ease; 5, the cover; 2 and 3, therings. Or, as m Fig. IV, in which 9 Ais the case; 11, the cover, screwedto the case at 12; 13, a projection of suitableshapc to -receive awrench; 14 and 15, neck and stoppers.

i Fig. II shows, on a reduced scale, a stand, U, re-

sembling a caster, which contains in the ringsvv V the bottles W, whichare to contain the liquids that are to be cooled. This is to be setintothe tub A, Fig. I, and immersed in the saline mixture. The shaft X,provided with wings y y', is then introduced in place of the shaft C,and, on being turned within the eentral space between thc bottles, thctemperature of the liquid is rapidly reduced.

The metallic vessels are to be tinned or coated with Asubstances notinjurious to health. What I claim, and desire to secure by LettersPatent, is-

Tbe combination of the hinged bevel-gears, the cenl tral shaft C, theattaehedieezing-cases R, and the wings Q, substantially as described.
